Value Collection P20007 Locking Cotter Pin 0.5 in Shaft

Product Description

The VALUE COLLECTION P20007 is a locking cotter pin designed for secure fastening in mechanical assemblies where vibration or dynamic loading could cause standard pins to back out. Built from RC 60-70 spring steel with a zinc-plated finish, this pin delivers hardness and corrosion resistance suited to industrial and trade applications. It measures 1.456 inches in length with a 0.5 inch shaft diameter and a wire diameter of 0.072 inches. The ring diameter ranges from 0.51 to 0.52 inches, providing a reliable locking fit. Maintenance technicians, millwrights, and field service professionals working on HVAC equipment, pump assemblies, and mechanical linkages will find this pin a dependable hardware choice.

This locking cotter pin is appropriate for use in residential and light commercial mechanical systems where positive pin retention is required. Typical applications include securing clevis pins, shaft pins, and pivot points in linkage mechanisms such as damper actuators, valve stems, and belt-drive assemblies. The spring steel construction maintains clamping tension across a wide range of operating temperatures, making it suitable for both indoor mechanical rooms and outdoor equipment installations.

Key Features

Compatibility

Designed as a standard locking cotter pin for mechanical assemblies requiring a 0.5 inch shaft diameter fit, including linkage, pivot, and clevis pin applications across HVAC, pump, and general industrial equipment.

Installation Notes

Installation is typically performed by maintenance technicians or mechanical service professionals. Always de-energize and lock out equipment before accessing pin-secured linkages or mechanical assemblies. Use appropriate pliers or pin installation tools to seat the ring securely around the shaft. Inspect mating shaft and hole dimensions for wear before installing a replacement pin to ensure proper retention.
